And when you have the space and the ability to build such pumped-storage hydroelectricity facilities, they require much cheaper and much more environment friendly materials.
And most already build hydroelectricity facilities can be retrofitted (although at high cost) to become pumped-storage hydroelectricity facilities.

- ElectricalUnion 3y agoWhat prevents you from digging a very deep downstream hole to store such water besides cost?
- kwhitefoot 3y agoI think you need a bigger word than digging, it wouldn't be a gang of navvies with shovels. The cost would be enormous, there are better ways to spend the money: solar, wind, better electricity networks, DC interconnects.
